Environmental Stress Screening Chamber ESS Test Chamber
For Industries Products Reliability Stability Verification
Environmental Stress Screen Chamber Applications:
Sanwood Environmental stress screening test chamber, also name as
ESS chamber, Rapid temperature change rate test chamber is widely
applied for electronic and electric products, components and
materials by constant high low temperature, temperature change ,
rapid rate temperature change ,damp heat etc environmental
simulation reliability test .
ESS Chamber Standard Compliance
GB/2423.1-2008 (IEC60068-2-1:2007) low temperature test method AB.
GB/T5170.5-2008 damp heat test equipment.
GJBl50.4 (MIL-STD-810D) low temperature test method.
GB2423.3-93 (IEC68-2-3) Test Ca: Constant damp heat test method.
GB2423.4-93 (IEC68-2-30) Test Db: Alternating Damp Heat Test Method
ESS Chamber features:
1.Graceful appearance, circularly shaped body, surface treated with
mist strips, and plane handle with no reaction.
Easy to operate, safe and reliable.
2. Rectangular viewing window for the observation of product under
test, equipped with sweat-proof electrical heating device that can prevent water steam from condensing into droplets, and
with high brightness PL fluorescent bulbs to provide light inside
the box.
3.Double-layer-insulated airtight doors, able to insulate the
internal temperature effectively.
4.Water supply system that is externally connectable, convenient
for refilling water into the humidifying pot and automatically
recyclable.
5. French Tecumseh is used for the compressor circulation system,
capable of removing the lubricant between thecondensation pipes and capillaries. environment friendly coolant is
(R23,R404A)
6.LCD display screen is used for the control unit, capable of
displaying the measured value as well as the set value and time.
7. The control unit has the functions of multiples segment program
editing, and with temperature ramp
8. Casters for ease of mobility, with strong positioning screws.
